4.0Ghz from a 2.66 proc!

All chips are not the same, once chip can do 4.0GHz with great vcore and temp and etc, and another will be able to do it with very high vcore and temp and etc, and one won't be able to do it at all.

but we have many owners here with a 920 oced to 4.0GHz with warranty.

qpi has replaced the fsb, its speed in a general manner is the speed that the cpu exchanges data with other components.

turbo just adds one more multiplier to the 20 you already have, in short its a form of oc, but turbo only oces one core out of 4.

this has all 4 cores running at 4.0GHz, no need for turbo nor will notice any difference from it.

Justin, who's is using 21 with a turbo? Also, Max Pc states and lists a comparison that it only makes small differences once you get up to 3.8Ghz but I think this was when i-7 first came out and they weren't using LC so.....  At what point does it become just bragging rights that it's running at 4.0 and not say 3.66? How much of a difference would there be before the ram or vid card bottlenecks the proc? Are there any charted study, you Vetern DS members know of? I'll even accept personal experience, all I know is it's going to be like going from Fiat to Ferrarri for me.

Ah wise Justin, did you save the tests so you can post them or load them on a website? I know there's no one answer, I've been doing this since DOS 5.. something. I miss the old mutli-game menu that I created by hand to optimize the hardware for each game that ran DOS4GW and Win 3.1 I don't miss having to set each IRQ by hand and moving hardware around to avoid conflicts though. I too am waiting for 6 core, I'll probably buy it right before 8 core comes out.

As far as other things like boot up, anti virus scanning, video compiling ect, they scale out till they hit a bottle neck, like RAM. So if you keep overclocking to 5.5ghz or beyond, most apps will just keep getting faster, until a different part of your rig slows it down.

not the 2.66 is the cpu's core speed, the qpi for the 920 is 4.8 GT/s, don't worry too much about qpi, for gaming and such you will not notice any difference between a 975 @ 4.0GHz with 6.4 GT/s qpi vs a 920 @ 4.0GHz with 4.8 GT/s qpi.

you can tell the difference upto 50 to 60 fps, but pass 60 you can't tell the difference anymore, which why we all say for smooth gaming at highest settings with high aa and af you need to enough gpu power to give you 50 to 60 fps.

for most games at 1900 x 1200 its takes 2 x 275 or 1 x 5870, for res under that 1 x 275 or 1 x 5850 will give you 50 to 60 fps.

crysis tho is a different story, it needs more then regular games so for 1900 x 1200 for crysis for example you would be better off with 2 x 5870, but other then crysis for most other games that will give you like over 100 fps which is all a waste.

at 50 to 60 fps, its all smooth game play, you don't see pauses, freeze, stutter, etc, etc, it all smooth.

with on-line games, other things come to play, your Internet speed/ping, distance from the server you are connecting to, that server's specs and Internet speed/ping.

crysis engine and coding is huge, its got over million lines of code, and sh*t load of texture data and shaders, search it and you find lot of info on it.

when ocing lot of things need to be adjusted, some of your mobo's voltages has be adjusted also.

I'm sure justin will fill in anything missed.

Originally posted by BriSleep Ok, so am I right then in assuming that the 2.66Ghz clock that the chip is saddled with is a QPI, or in the old days FSB of 133Mhz? I'm not assuming, I think I read it somewhere. Is it also not right that the average set of human eyes can't see an FPS past 26 or maybe 30 for the younger folks? What do you get out of a faster frame rate? How much of this speed can be handled in an internet game? When I used to play Descent3 online the ships and missles would actually disappear and re-appear as they moved along, the only accurate way to track someone was sound because it always followed exactly where they are. I know, that has to do with packets and all kinds of other stuff but now that we have HT multi-core, are most of those things handled? What is it in the game Crysis, which is hear has a very disappointing end, that causes it to be such an overall system engine stresser that most games don't have?   Finally, does the rest of the motherboard get a voltage increase too and an increase in heat because of it or is that the reason behind having QPI now instead of FSB?   BTW, thanks for all this, this is gold you can't get from a magazine subscription.
